제목 | A preliminary study on CO2 removal from PFBC flue gas using aqueous potassium carbonate solution |
초록 | PFBC (pressurized fluidized-bed combustion) integrated with Benfield carbonization could be an alternative power technology due to its CO2 emission reduction as well as compact size. Benfield process uses aqueous hot potassium carbonate promoted by diethanolamine (DEA) as CO2-absorbing medium. However, because DEA suffer massive degradation during thermally regenerated cyclical process, thermochemically stable rate promoter should be suggested. In this study, a preliminary investigation was conducted to improve hot potassium carbonate process. Optimum reaction condition including CO2 partial pressure, reaction temperatures for temperature swing was explored by measurement of vapor-liquid equilibrium. The effects of additives on reaction kinetics were investigated using stirred-cell reactor for both promoter (inorganic or amine) and corrosion inhibitor. The experimental results could enhance CO2 capture performance resulting in the increases of generating efficiency. |
